which at little or no increase in cost the efliciency is materially increased.

The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a longitudinal section; Fig. 2 an outer end view; Fig. 3 is an end view; Fig. 4 is a side view of a ventilator applied to the side of a railway car. Fig. 5 is a longitudinal section through the top of a car on which the ventilator is mounted.

Referring to the embodiment of the invention illustrated, the pipe A forms the entrance for the bad air which is to be withdrawn. In line with this entrance is an outlet B between the bases of the pair of cones C whose axes extend transversely to the axis of the entrance pipe A. Over the outlet B is a hood D of cylindrical shape arranged a slight distance beyond the bases of the cones C and attached to the inlet pipe A and preferably also supported at the outer side by thin supports E designed to offer a minimum amount of obstruction to the passage of air and gases. The hood D being cylindrical, the outer faces of the cones are inclined away from the hood. The ventilator is arranged in use in such a position that the wind blows against the side of the cylindrical hood, as shown by the arrows in Figs. 2 and 3. The hood D extends completely around the cones and over substantially their entire lengths, so that the wind does not directly strike the cones but only blows over their ends and the open ends of the cylindrical hood. I find by experiment that this protecting of the ends of the cones from the direct con tact of the wind causes a material increase in the efliciency of the ventilator, that is to say, in the speed with which it withdraws air from a car or other compartment for a given rate of wind blowing against the ventilator on the outside.

The ventilator 1s adapted for use in various hinged ventilating window G on the deckplate H of a car, between the upper and lower roofs J and K. The opening of the ventilating window G to a greater or less extent will control the withdrawal of air from the car, and the ventilator will main tain a steady and strong suction as long as the car is moving and creating a wind against the side of the ventilator.

The long hood D, besides increasing the ventilating draft, protects the outlet to a great extent against the entrance of cinders, dust and rain. WVhere the ventilator is to be used in the position of Fig. 4 small openings L may be provided at the apexes of the cones for the escape of any water which may be blown into the space between the cones. The flanges M substantially prevent the escape of such water into the inlet pipe A.

What I claim is 1. A wind operated ventilator, having an outlet in line with the entrance, a hood over said outlet and a face extending from said outlet at an inclination away from said hood, said hood covering the entire length of said inclined face, and extending slightly beyond the same to protect the ends thereof from the wind, in combination with a structure to be ventilated, said ventilator being mounted on said structure and being so arranged that in use the wind shall blow against the side of said hood.

2. A wind operated ventilator, having an outlet in line with the entrance, a conical face with its base adjacent to said outlet and a cylindrical hood over said outlet and extending around said conical face and over its entire length, and extending slightly beyond the same to protect the ends thereof from the wind, in combination with a structure to be ventilated, said ventilator being mounted on said structure and being so arranged that in use the wind shall blow against the side of said hood.

3. A wind operated ventilator, having an outlet in line with the entrance, a pair of cones with their bases forming the sides of said outlet and a cylindrical hood over said outlet and extending around said cones over their entire length, and extending slightly beyond the same to protect the ends thereof from the wind.

4:- The combination with a car of a wind operated ventilator having an inlet pipe A, a pair of cones C 0n the end of said pipe with their bases facing and slightly separated from each other and their axes in line with each other and a cylindrical hood D over the space between said cones and extending around the entire lengths of said cones and extending slightly beyond the ends thereof so as to protect said ends from the wind, said cones having openings L in their ends for the escape of water, and said hood being located upon a car with its axis transverse to the direction of travel.

5. The combination with a car of a wind operated ventilator having a horizontal inlet pipe A, a pair of cones C on the end of said pipe with their bases facing and slightly separated from each other and their axis vertical and a cylindrical hood D over the space between said cones and extending around the entire lengths of said cones and extending slightly beyond the ends thereof so as to protect said ends from the wind, said cones having openings L in their ends for the escape of water, and said hood being located upon a car with its axis vertical.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
